Description

The invention relates to a cleaning robot for a motor vehicle, in particular a spherical cleaning robot for a motor vehicle, and a service station for cleaning a motor vehicle, in particular using the spherical robot. Further aspects of the invention relate to a method for operating the cleaning robot in a motor vehicle and to a method for operating the service station.

Today's vehicles already have a large number of assistance systems that provide computer-based support to the driver in a large number of driving situations. Such assistance systems can use sensors to record a large number of measurement data, which by far exceed the human senses. In addition, the speed of these assistance systems significantly exceeds human reaction times. Known driver assistance systems are, for example, lane departure warning systems, brake assistants for pedestrian detection and adaptive cruise control systems, in particular for traffic jam situations.

By using such assistance systems, the driver's autonomy with regard to his driving decisions is increasingly transferred to the vehicle or to the control units operating in it. At the end of these developments, there is an autonomous vehicle that can maneuver completely without human intervention. A fully automated passenger transport is possible by means of such an autonomously driving vehicle.

So far, such autonomously driving vehicles have generally been licensed for individuals and / or are not licensed for use on roads without additional monitoring by a driver. With regard to maintenance and care, these autonomously driving vehicles differ little from other privately owned vehicles. As a rule, the owner (s) will take care of the maintenance and energy supply of the vehicle.

However, a wide variety of mobility concepts already exist today, especially in urban areas. With so-called car sharing, a large number of users access the vehicles in a vehicle fleet independently of one another and for a limited time.

Since the fleet vehicles are only tied to a specific user for the period of actual use, unused parking time of the vehicles can be minimized.

Car sharing concepts are also known for other vehicles, such as bicycles, scooters or vans. Without being limited to passenger cars, reference is made below only to car sharing in a representative manner. The invention can also be used in the context of ride pooling and ride hailing.

Furthermore, an autonomous vehicle fleet can denote a fleet of private vehicles that are temporarily made available for driving services, in particular for autonomous driving services. In the aforementioned cases, a fleet operator is to be understood as the provider of an application, the application being used to connect users and providers of driving services. Under certain circumstances, the fleet operator can be a vehicle manufacturer or a service partner of such.

A distinction is made in particular between centralized and decentralized car sharing concepts. With central car sharing concepts, vehicle use must always be started and ended at fixed stations. It is therefore essentially a short-term classic vehicle rental. In the case of decentralized car sharing concepts, on the other hand, vehicle use can begin and end at any point in an operating area of the fleet provider. In particular, decentralized car sharing concepts have the potential to significantly reduce the total number of vehicles required, since the fleet vehicles will be available in a self-organized manner and with sufficient density in the operating area if there is a sufficient number of users and vehicles.

However, especially with decentralized car sharing concepts, the energy supply, maintenance and care of the vehicles represent a challenge. On the one hand, employees of the fleet provider can be used to refuel and clean the fleet vehicles. However, this increases the personnel costs and thus the costs of the car sharing concept significantly. Alternatively, the users of the autonomous vehicles can be prompted by appropriate incentives to carry out the necessary service trips. However, there is a risk of inadequate maintenance or vehicle breakdowns. In addition to the operability of the individual vehicles, it is also necessary to maintain the functionality of the fleet. In particular, the decentralized car sharing concepts require a certain minimum number of vehicles ready for use at all times. This is the only way to ensure sufficient availability of vehicles for users.

The invention is therefore based on the object of overcoming or at least reducing the problems of the prior art and of providing a solution for performing interior cleaning on a vehicle, for example an autonomous fleet vehicle, which takes into account the functionality requirement of the entire fleet .

The object is achieved by the subjects of the independent claims. Preferred further developments are the subject of the dependent claims.

A first aspect of the invention relates to a method for operating a motor vehicle, the motor vehicle used in the method according to the invention having at least one vehicle window, at least one operating element and / or at least one display and at least one vehicle seat. The display can also be designed as an operating element, for example as a touchscreen or the like. The motor vehicle also preferably has further elements, in particular a control unit and a communication module designed for communication with a service station. The last-mentioned elements are designed in particular to convey an autonomous drive of the motor vehicle to a service station, as explained in detail below.

In the method according to the invention, preferably when it is carried out by an autonomous service station, at least single-layer coatings are applied to the at least one vehicle window, to the at least one operating element and / or display and to the at least one vehicle seat. The at least single-layer coatings are preferably applied by machine, preferably by a robot arm or by a tool attached to the robot arm. The coatings used are preferably different for different elements on which the coatings are applied, as will be explained in more detail below.

During operation of the vehicle, in particular during operation of the vehicle as an autonomous fleet vehicle, for example in car sharing, ride pooling or ride hailing, soiling collects on the covers and not on the elements below. For example, hair and dust collect on the cover of the vehicle seat and fat deposits, for example fingerprints, collect on the cover of the display or control element. The at least single-layer covers thus advantageously prevent the elements underneath from being soiled.

In the method according to the invention, the at least single-layer coatings are also removed together with the contaminants deposited thereon. The coatings are also preferably removed in an autonomous service station and particularly preferably by machine, preferably by a robot arm or by a tool attached to the robot arm. Alternatively, the coatings or at least some of the coatings are preferably removed by hand by a user and / or as required.

The method according to the invention advantageously enables a vehicle interior to be kept clean without the need for complicated automated cleaning of the complex geometries in the interior of the vehicle. Such an automated cleaning of the various surface types of a vehicle interior, in particular of displays, seats, windows and operating elements, would be associated with a high level of effort due to the different materials of these elements. In particular, in such methods, it would be necessary to identify the dirt and choose the right cleaning tool and / or robot, which at least so far has resulted in a lower cost efficiency than cleaning by humans. In the process according to the invention, such automated cleaning becomes obsolete by the application of coatings to protect against contamination.

As already stated, the application and / or removal of the at least single-layer coatings takes place autonomously in a service station. The vehicle is preferably an autonomous vehicle that visits a service station regularly or as required, that is, depending on a service requirement. The covers are preferably applied in response to the determination of a corresponding service requirement, for example based on a user input in the vehicle, which indicates that existing covers are soiled. In such a case, the soiled coatings are particularly preferably removed autonomously, in particular by machine, before new and clean coatings are also applied autonomously, in particular by machine. Advantageously, the application and removal of coatings that protect against soiling can be automated more easily than cleaning various surfaces in the vehicle interior.

Furthermore, in the method according to the invention, a multi-layer coating of a plurality of transparent foils is applied in each case to at least one vehicle window, on at least one operating element and / or on at least one display of the motor vehicle (which can also be designed as an operating element). In other words, one is applied Stack of films on the aforementioned elements, each film being adhesively bonded to the underlying film. Furthermore, each film preferably has a superficial release coating which enables a film located above it to be easily detached.

The application of film stacks advantageously enables the service intervals to be lengthened. In other words, the service station has to be visited less often, which advantageously increases the availability of the vehicle for the vehicle fleet. An upper, soiled film can be removed by a user of the vehicle as required. After removal, the protection of the respective element is retained by the film underneath. The use of film stacks to protect surfaces from soiling is known to the person skilled in the art, for example from motor sports, where comparable solutions are used for the visors of helmets. A refuse container for receiving the films removed by a user is advantageously provided in the vehicle. This garbage container can advantageously be removed the next time you visit the autonomous service station.

With regard to the at least one vehicle window of the motor vehicle, in particular the windshield, rear window and side windows, at least one film, preferably a plurality of films of a film stack, is applied to the outside and / or to the inside of the at least one vehicle window. In this way, the vehicle windows can be protected both from environmental pollution on the outside of the window and from user-related pollution on the inside of the window. Providing glass or plastic panes with protective films is much easier to automate than machine cleaning of such sensitive elements as panes of glass.

Furthermore, each of the transparent films preferably has at least one tear-off edge provided with a tear-off indicator. In the context of the present application, a tear-off edge is understood to mean an edge which is designed to facilitate the removal, in particular the peeling off, of an uppermost film of a film stack. For this purpose, in the area of the tear-off edge, for example, an adhesive coating of the foil is less strong than in other areas of the foil stack and / or the foil protrudes slightly from the foil stack in this area. The provision of a tear-off edge thus advantageously facilitates both the manual and the machine removal of an uppermost film of a film stack.

The tear-off edge can also advantageously be easily recognized by the tear-off indicator. The recognizability is preferably increased for a user who should be able to easily pull off the topmost film. In a likewise preferred embodiment, the tear-off indicator improves the perceptibility of the tear-off edge for a robot arm of an autonomous service station designed to remove, in particular peel off, the topmost film. According to this embodiment, the tear-off indicator is preferably machine-readable, for example by means of a bar code, surface structuring or the like. Such a machine-readable tear-off indicator is particularly preferably designed to be invisible to the human eye, for example due to a high degree of transparency, a very small spatial extent and / or by using a tear-off indicator that can only be detected outside the frequency range of the human eye. Such a machine-readable tear-off indicator advantageously does not restrict the visibility for a user through the at least one film.

In a particularly preferred embodiment of the method according to the invention, the machine-readable tear-off indicator is designed as a barcode. The barcode is advantageously suitable for encoding further information. This additional information can, for example, define the type of film, in particular its size and geometry. The machine-readable tear-off indicator can thus advantageously be used in the method according to the invention to provide a robot arm with the information required to replace the film. The barcode also preferably contains information about the number of remaining foils in a foil stack or the like.

In a likewise preferred embodiment of the method according to the invention, a washable seat cover is applied to the at least one vehicle seat. The seat cover used in the method according to the invention has at least one receiving point, which is designed to receive at least one holding tool of a robot arm. The seat cover used is therefore explicitly designed for handling by means of a robot arm. Furthermore, the washable seat cover is also preferably removed in the method according to the invention. The seat cover is preferably applied and removed mechanically and by a correspondingly designed robot arm of an autonomous service station. The pick-up points allow the pliable object to be handled by the robot.

In a likewise preferred embodiment of the method according to the invention, a washable seat cover is used which has at least one fastening element for fastening the Has washable cover on a vehicle seat. The fastening element is preferably formed by at least one, preferably a plurality of magnets sewn into the cover. This has the advantage that the fastening elements also improve the positioning of the cover on the vehicle seat when the cover is applied by machine, the vehicle seat likewise having a plurality of sewn-in magnets.

Alternatively, the at least one fastening element is preferably designed as a Velcro fastener or snap fastener and the vehicle seat has corresponding counterparts.

Another aspect of the present invention relates to a service station for a vehicle, in particular a service station designed to autonomously carry out the method according to the invention. The service station according to the invention has a service module designed to clean the interior of the vehicle. The service module has at least one robot arm, in particular a stationary robot arm. The robot arm is designed to apply and / or remove at least one-layer coatings on at least one vehicle window, on at least one operating element and / or display or on at least one vehicle seat of the vehicle. In particular, the robot arm has at least one tool designed to apply and / or remove at least one-layer coatings on the aforementioned elements.

According to a preferred embodiment of the service station according to the invention, the robot arm has at least one first holding tool designed to engage in at least one receiving point of a washable seat cover. The first holding tool is designed in particular to pull off a pliable cover from a vehicle seat by engaging the receiving point, for example a loop, and exerting a force on the cover. The holding element is also preferably designed to pull or apply the cover to the driver's seat. For this purpose, the first holding tool also engages in a receiving point of the coating, which can be different from the holding point used for peeling off. The pulling up is preferably supported by fastening elements, in particular magnetic fastening elements.

In a likewise preferred embodiment of the service station, the robot arm also has a second holding tool that is designed to pull a film off a substrate. The second holding tool is designed, in particular, to grip a tear-off edge, for example a slightly protruding tear-off edge, of a film and to remove the film from the substrate by applying a tensile force. Furthermore, the second holding tool preferably has a reading head designed to recognize a tear-off indicator. The reading head has in particular an optical detector for detecting a tear-off indicator. According to a preferred embodiment of the method according to the invention, the tear-off indicator is designed as a barcode. The reading head of the second holding tool is thus preferably designed as a barcode scanner. The reading head is also preferably connected to a control unit designed to control the robot arm. The control unit is also preferably designed to receive and evaluate further information encoded by the barcode from the reading head.

The robot arm also preferably has a third holding tool designed to apply at least one film to at least one pane and an operating element and / or display. Furthermore, in addition to the functionalities already described above, the second holding tool is alternatively also preferably designed to apply at least one film to at least one pane and an operating element and / or display.

The service station is preferably part of an infrastructure for the autonomous cleaning of a vehicle, as described in greater detail below. The method according to the invention, in particular the application and / or removal of at least one-layer coatings, is preferably carried out within the service station by the service module. The service station is thus designed to be used in the method according to the invention and has, for example, a (second) communication module set up for communication with a motor vehicle and / or a server of a fleet operator. The (second) communication module is, for example, a WLAN or mobile radio module and is preferably designed to carry out Car2Car or Car2X communication.

The second communication module is preferably designed to communicate in accordance with a communication protocol that is used by a communication module of the vehicle and / or by the server. The service station according to the invention also has a (second) control unit which is designed to carry out the method steps of the method according to the invention. The control unit is designed to control the communication module and the service module.

The service station according to the invention is preferably part of a service infrastructure that has at least one service station and preferably a multiplicity of service modules arranged in the service station or associated therewith, which are arranged in an operating area of the autonomous vehicle fleet. The number and density of the service stations and service modules is preferably adapted to the number of autonomous fleet vehicles and the need for service actions or the frequency of service actions required. Each service station is preferably designed for communication with autonomous vehicles, the service modules, a server and / or other service stations.

In the context of this service infrastructure, the available (and suitable) service modules are preferably determined by a service station to which information on a vehicle's service requirement was transmitted from a vehicle or the server. The service station also takes into account the utilization of the service modules. The suitability is preferably determined automatically, for example on the basis of a database, by means of at least one look-up table, LUT, by means of at least one algorithm and / or by means of artificial intelligence. Alternatively or additionally preferably, the at least one suitable service module is determined in part by a user input, for example an employee of the fleet operator in response to an input request.

As part of the service infrastructure, the vehicle is also preferably driven autonomously to the available (and suitable) service module that has been determined. The journey takes place after the available (and suitable) service module has been determined. If the autonomous vehicle in question arrives at the available and suitable service module or the corresponding service station, a service action that has been determined and corresponding to the service requirement is carried out partially or fully autonomously.

In the context of the present application, a service requirement of the vehicle is preferably understood to mean that a service interval for changing at least one of the at least one-layer covers has expired. A service requirement is also preferably understood to mean that, based on a user input or based on a detected detector signal, for example an interior image, soiling of at least one of the at least one-layer covers is detected. As a result of such a service requirement, the vehicle preferably visits the service station according to the invention, where the method according to the invention for operating a motor vehicle is preferably carried out fully or partially autonomously.

In addition, a service requirement of the vehicle in the context of the present application can relate to a low level of the energy store of the vehicle, for example a low state of charge, SOC, of an electrical energy store or a low level of a tank for fossil fuels or hydrogen. A service requirement can likewise preferably relate to an error message from the vehicle, particularly preferably an OBD2 error message. Furthermore, the service requirement can preferably relate to a message regarding the expiry of a service interval, for example for an oil change.

In the method according to the invention, a service action is an action on the vehicle in order to transfer it from the present actual state to a desired target state.

A type of service action is preferably determined on the basis of the type of service requirement determined, so that a service action is understood to mean an action on the vehicle that corresponds to a specific service requirement. For example, cleaning the vehicle corresponds to soiling the vehicle. In particular, soiling of at least one of the at least one-layer coatings corresponds to removing the soiled single-layer coating and applying a new at least one-layer coating to the corresponding element. Furthermore, a low filling level of the energy store preferably corresponds to a filling of the energy store and to a detected error message of the vehicle a maintenance or repair of the vehicle. If soiling of a coating is detected, but there are also other, non-soiled layers of a stack of foils, the detection of a soiled coating based on a user input preferably corresponds to an output of a request to the user to remove the soiled foil.

The method steps of the method according to the invention can be implemented by electrical or electronic parts or components (hardware), by firmware (ASIC) or by executing a suitable program (software). The method according to the invention is likewise preferably realized or implemented by a combination of hardware, firmware and / or software. For example, individual components for performing individual method steps are designed as a separately integrated circuit or are arranged on a common integrated circuit. Individual components set up to carry out individual process steps are also preferably on a (flexible) printed circuit carrier ( FPCB / PCB), a tape carrier package (TCP) or another substrate.

The individual method steps of the method according to the invention are also preferably embodied as one or more processes that run on one or more processors in one or more electronic computing devices and are generated when one or more computer programs are executed. The computing devices are preferably designed to work together with other components, for example a communication module and one or more sensors or cameras, in order to implement the functionalities described herein. The instructions of the computer programs are preferably stored in a memory, such as a RAM element. The computer programs can, however, also be stored in a non-volatile storage medium, such as a CD-ROM, a flash memory or the like.

A person skilled in the art can also see that the functionalities of several computers (data processing devices) can be combined or combined in a single device or that the functionality of a specific data processing device can be distributed across a number of devices in order to carry out the steps of the method according to the invention without deviate from the method according to the invention described above.

The method according to the invention is preferably carried out in a system for carrying out a service action on a vehicle. The system for performing a service action has at least one autonomously driving vehicle, which has at least one first sensor designed to capture environmental data and at least one second sensor designed to capture vehicle data.

1 shows a schematic representation of a vehicle interior, having a vehicle window 100 , especially a windshield 100 , a control element 101 , especially a rotary control 101 , and a display 102 , especially a touch screen 102 .

There is a foil on each of the aforementioned elements 104 Applied as a dirt-absorbing coating. This is on the rotary control 101 a single layer film 104 applied and are on the windshield 100 and on the touchscreen 102 multi-layer film packages 105 , consisting of a large number of transparent foils 104 upset. The slides 104 or foil packages 105 were thereby in the method according to the invention, in particular by means of a robot arm 951 , 952 , as in 4th shown, applied.

Any of the slides 104 also has a tear-off edge to which the film adheres 104 on the element below, for example the rotary control 101 , or on the film underneath 104 is reduced. As a result, the slide is standing 104 in the area of the tear-off edge slightly from the element or film below 104 and can be more easily by a user or a second holding tool of a robot arm 951 , 952 gripped and from the underlying element or film 104 can be deducted as in 1 illustrated by the arrows in the pull-off direction.

The tear-off edges of the foils 104 are also through tear-off indicators 107 , 108 marked. The tear-off indicators 107 are used as optical indicators, especially as on the foils 104 printed optical indicators designed to allow a user to easily perceive the tear-off edge. The tear-off indicator 108 is as a machine-readable tear-off indicator, especially as a barcode 108 , educated. The barcode encodes 108 the information that it is located near a tear-off edge. In addition, the barcode preferably encodes further information, such as information on the size and geometry and / or on the type of the windshield 100 . This enables an autonomous service station 90 , after peeling off a dirty film 104 from the windshield 100 without further ado a suitable new slide 104 for the windshield 100 to determine. The barcode 108 can also encode how many slides 104 still in the stack of foils 105 to be removed. Thus, during a service in an autonomous service station 90 be decided that the stack of foils 105 is exchanged if less than a predetermined number of residual foils 104 on the stack of foils 105 remains. In addition, the barcode 108 further information for a service station 90 encode.

Due to the multitude of foils 104 are in the vehicle interior of the 1 the windshield 100 , the rotary control 101 and the display 102 protected from contamination. Instead of these elements, soiling is deposited on the foils 104 from. Thus, by removing a soiled top film 104 from a foil package 105 or by replacing a dirty film 104 through a new slide 104 a clean appearance of the underlying element can easily be restored.

2 shows a schematic representation of a vehicle seat 103 with a coating applied in the method according to the invention 106 . The vehicle seat has a seat cushion, a backrest and a headrest. The Indian 2 coating shown 106 is designed for the headrest and in particular designed largely form-fitting with the headrest. The coating 106 is washable and has two eyelet-shaped mounting points 109 on. These pickup points 109 are designed to have a first holding tool of a robot arm 951 , 52 in the pickup point 109 engages, for example around the cover 106 from the headrest. Furthermore, the coating 106 a plurality (not shown) magnetic fastening elements and the headrest also has a plurality (not shown) corresponding magnetic fastening elements. The interaction of these fastening elements enables the application and alignment of the coating 106 on the headrest improves and the applied coating remains 106 fixed on the headrest.

3 shows a schematic representation of a first service module 95 for cleaning the interior of the vehicle 10 . To clean the interior of the vehicle 10 this moves into the service module 95 one to get there on a stop position 953 to come to a stop. Once the vehicle 10 on the stop position 953 comes to a stop, the vehicle doors open 18th of the vehicle 10 automatically. This is preferred by the control unit 92 of the first service module 95 initiated that directly with the control unit 40 of the vehicle 10 communicates. Once the vehicle doors 18th are opened, become a first robotic arm 951 and a second robotic arm 952 in the vehicle 10 introduced.
